Saharan dust that blew off the west coast of Africa on June 22, 2007, continued its westward journey across the Atlantic Ocean the following day. Moderate Resolution Imaging Spectroradiometers (MODIS) on NASA’s Terra and Aqua satellites tracked the dust plume’s progress. This image was composed from a combination of Terra and Aqua observations on June 23, 2007. Terra recorded the dust plume in the eastern Atlantic around 13:00 UTC, and Aqua recorded its progress in the western Atlantic around 14:20 UTC.
The high-resolution image of this dust plume has a resolution of 500 meters per pixel.
